What Does an Alternator Do?

You know what your engine does, you know what your transmission does, but just what does an alternator do? Many customers ask our service team about this component every day, and you might be surprised to learn just how important it is for the performance of your vehicle. The alternator sends power to your car’s electrical system, using energy provided by the engine. While some people think that the battery powers a car, the battery only gets a car going. It’s the alternator that keeps your car running smoothly. That’s why it’s so crucial for your car’s performance.

Is My Alternator Failing?

You know your car best, so if you’re noticing some unusual issues while driving through Texas, could your problem be the alternator? Here are some warning signs that we mention to our customers. See if any of these seem familiar:

• Battery warning light appearing on the dashboard
• Dim headlights or interior lights
• Burning rubber smell under the hood
• Devices not charging
• Whining or screeching sound after the vehicle has started
• Unable to start

Is My Problem the Battery or Alternator?

Are you dealing with a failing alternator or a failing battery? If you’ve recently jump-started your vehicle, think about what happened. Did your car die immediately after the jumper cables were removed, or did it hold the charge? If your car couldn’t stay powered without the jumper cables, you’re probably dealing with a failing alternator. If the car can hold the charge without the cables, it means that a dying battery is more likely to be your issue.

How Much is an Alternator?

Alternators generally last around 80,000 to 150,000 miles – or seven years, on average. But different factors can affect wear, like the quality of your alternator and the severity of your driving conditions. So, how much is an alternator when you need a replacement? It’s difficult to make broad estimates, so it’s always a good idea to call the service department for a free quote. The cost of an alternator for a compact hatchback is different than a pickup truck, but our technicians will run through all the details with you!
